HYDBOCARIBON VAPORIZER AND BURNER.

Patented Oct. 13, 1914.

Application led March 5, 1910. Serial No. 547,402.

To all whom it may concern.'

Be it known' that I, EDWARD MEL'rzER, a citizen of the United States, residing in the city of New York, borough of Manhattan,

county and State of New York, have invented a certain new and useful Hydrocarbon Vaporizer and Burner, of which the following is a specification.

This invention is a hydrocarbon vaporizeiand burner, and embodies an improvement,

in a certain particular, upon 'the apparatus disclosed in a prior application filed by me on Nov. 19, 1908, Serial No. 463,814.

In the apparatus described in the aforesaid application, a gaseous fluid, under pressure, preferably steam, is permitted to enter a series of nozzles, and the suction produced thereby operates to draw in and commingle with said steam, petroleum and air, thereby producing a suitable gaseous 'combustible In said apparatus, however, the steam is superheated but no means is provided for preheating the oil.

The object of the present invention is to increase the eliciency of the apparatus forming the subject matter of said prior appli-V cation, and with this object in view, embodies means for preheating the petroleum or other combustible, prior to mixing it with the steam or air. i

In the preferred embodiment of the invention, the oil is heated by causing it to circulate in a pipe, coil or other container, while said container is exposed to the heating action of the superheated steam employed in the apparatus. I

In the accompanying drawings I have illustrated one-practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a plan view of a vaporizing burner embodying this invention. Fig.2 is

an enlarged vertical sectional elevation on line 2-2 of Figs. l and 3Q Fig. 3 is a vertical' sectional elevation on line 3 3 of Fig. 2. Fig. Lis a plan View of a portion of the burner.A

The burner, or more properly a combined vaporizer and burner, consists of a cylinder,

A, provided at one end with a frusto conical head, a; and a vaporizing plate, B. Said head has a series vof apertures or openings,

a', for the ingress of air into cylinder or chamber, A, and, also,other larger `apertures, o, which are adapted to be partly or wholly closed by suitable shutters, C, thereby providing for regulating the volume of air supplied to the apparatus.

IDdesignates a casting which is supported4 suspended from the cylinder,

on a shelf, d.

A, said casting being provided with an interior chamber, e, termed a steam chamber,

preferably annular in shape, and connected with such chamber is means for supplying Casting, D, is provided with a front plate,

e', and a rear plate, e2, said front and rear plates forming, respectively, the front and rear walls of chamber, e. Plate, e, is preferably made integral with casting, D, but plate, e2, is removable to permit of the introduction of an oil coil, J, within the steam chamber, e. The front plate head, e, is provided with a series of openi gs, f, corresponding in number and position to openings, Z), of vaporizing plate, B, and in these openings,'f, are screwed jet nozzles, F. Said nozzles are tapered and extend forwardly from plate or head, e, into the openings, o, said nozzles being of less diameter than the openings, b, whereby free spaces are provided between the walk of openings Z), and the outer surfaces of nozzles, F.

The burner is provided 'with means for removing any sediment whfich may lodge or accumulate in openings, Z), plate,- B, or in the passages of nozzles, F, whereby the steam passage or passages may be kept@ in an unobstructed condition, and

thus permit the steam and combustible vapor to pass freely therethrough. As shown, 4the .sediment removing means consists of stems or spindles, Gr, extending through stuffing boxes, g, and by reciprocating said spindles when required, it will be obvious that openings, 4b and f, may be kept clear.

The salient feature of the present invention consists in preheating the oil, preferably in the steam chamber, e, and, with this object in view, an oil pipe, J, having an inlet pipe, j, is coiled Within said chamber so that oil passing through said coil becomes pre-4 heated by the steam contacting With the eX- terior of said coil. As shown more clearly in Fig. 3, casting, D, is provided with a hub or sleeve, i, and into this sleeve is fitted and second anshort tube, I, Whichmay be termed an oil vaporizing chamber the inner end of Which is positioned opposite to a depression, J, in the vaporizing plate, B. The outer end of tube, I, is closed by head, and to this head is attached onemend, j', of the oil pipe, J, whereby the preheated oil is supplied to tube, I, and the chamber of said tube I constitutes a vaporizing chamber for the reason that the preheated o il is converted into vapor Within the chamber of said tube I. The oil is fed to the pipe, J, preferably by means of the suction produced by the steam passing through 'openinggsjend 5. Oil pipe, j, is rovided near its inlet to tlie'burner with a va Ve, j, Whereby the amount of oil supplied to the burner may be' controlled or regulated.

K designates a pipe attached to casting,

D, and communicating with chamber, e, sol

as to carry oil1 any Water of condensation which may accumulate in chamber, e, said" pipe lbeing provided With a stop cock, c.

The operation of the apparatus will be apparent from the foregoing descrtion,

but it may be described as follows team from any suitable source is supplied to pipe, E, is superheated therein, and conveyed thereby to chamber, e, Whereas the oil, preheated Ain pipe, J, is fed thereby into tube, I, and projected in the form of a sprayor jet against the depression, b, in Vaporizing vplate, B. The steam issues from nozzles,

in the form of jets which are: projected through openings, b, into the mixing cham ber of cylinder, A, and these steam jets draw or entrain the vaporized fuel into said mixing chamber. Simultaneously 'with these operations, air is drawn or eithausted into the chamber of cylinder, A, and the steam, fuel and air are thus thoroughly commingled in said chamber and ignited therein. The combustion thus up heats vaporizing plate, B, suiciently to vaporize, in Whole or in art', the oil thrown against it, which vapor is then entrained by the jets from nozales, I?, and passes through o enings, b, into the chamber of cylinder, A, W ich letter may be properly termed a mixing chamber.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is:

1. In a hydrocarbon Vyaporizer and burner, the combination of an oil vaporizin,l chamber, a heating chamber externally 0f said vaporizing chamber, means for introducing a heatin agent to said heatingchamber, a coiled oil pipe within said heating chamber, 'an oil vaporizing plate provided with openings, and passages leading from the vapori' ngcrmb 1 and heating chamber to the said openines in the eapcriz ing plate. l

2. In a hydrocarbon y: the combination of an c I n ber, a heating chamber 'ernally said vaporizing chamber, me -tor introducing a heating agent to said heating chamber, a coiled oil pipe Within said heating chamber, an oil vaporizing plate. provided with open" ings, passages leading from the vaporizinrf chamber and heating chI i. er'to openings in the Veporin3 -ate, am. ing chamber forwardly of the tape late into which the 'openings in izing late lead.l y

3. n a hydrocarbon teporizer the combination of an oil Vaporizing c ber, a heatingI chamber externally of said vaporizing chamber, means for introducing a heating agent to said heating chamber, coiled oil pipe Within said heating chamber, said heating chamber being provided Wit det-achablelplate for introducing the ce oil pipe therein.

In testimony whereof I have signed name to thi e "ritieni-,ier in the presario.
